MODFLOW and HYDRUS Modeling of Groundwater Supply Prospect Assessment for Distant Pastures in the Aksu River Middle Reaches

As in many regions across the world, southeastern Kazakhstan is subjected to ongoing water-resource depletion. The livestock sector already a major natural water resource consumer, with groundwater use becoming its supply strategy. Remote pasture infrastructure development requires new resources allow area circulation. distant pastures middle reach of Aksu River consist three pastures, total 32,450 ha and permissible number 3245 heads. HYDRUS-1D transport model MODFLOW groundwater-flow simulated complex prospect hydrogeological scenarios consumption 302.4 m3 per day for keeping on pasturelands. During pumping watering, projected production well drawdowns were quantitatively evaluated. findings show that flow rate equals 288 m3/day during season 95 outside season. While wells No. 2 3 can be considered reliable, 1, an additional needed. To maintain wells’ less than 6 m, reduction 216 70 m3/day, respectively, required.
